Sean made a subtle attempt at showing Catherine was his girlfriend in the calculus class, and everyone in the classroom felt it.
It seemed their relationship was stable. Students who came to Sean's class intended to see how embarrassed Catherine and Sean could be. But, they indirectly acknowledged the relationship and showed how sweet they could be, which was contrary to what the audience had in mind.
The way Sean looked at Catherine in class was so gentle. He turned into a kind and loving man. The picture of him with Catherine as they imagined was so lovely. Sean taught the girl he liked step by step with enough patience and detailed explanation. His voice was subtle and sweet. Catherine nodded, behaving like a good girl. Their interaction was in harmony, which was nothing out of sorts.
